大学新生负性生活事件和 神经质及运动频次与抑郁症状的关系.

Objective: Analyzing the relationship between negative life events and depressive symptoms in university freshmen, and the mediating effects of neuroticism and the moderating role of exercise frequency. Methods: A sampling of 8 079 university freshmen, and the Patient Health Questionnaire was used to assess depressive symptoms, the Eysenck Personality Inventory-Neuroticism subscale to assess neuroticism, the self-administered questionnaire to assess the number of negative life events that the participants had experienced and the exercise frequency. Model 4 in the Process plug-in was used to test the mediating effect of neuroticism, and Model 7 to test the moderating role of exercise frequency. Results: The numbers of negative life events were positively correlated with the depressive symptoms scores ( r = 0.16 P < 0.01), and were positively correlated with the neuroticism scores (r =0. 26, P < 0.01) . The neuroticism scores were positively correlated with the depressive symptoms scores (r = 0.52, P < 0.01) . Neuroticism score partially mediated between negative life events and depressive symptoms score, with a mediating effect of 78.4%, and exercise frequency score moderated between negative life events and neuroticism scores ( beta = 0.05 P = 0.032) . Conclusion: Negative life events are associated with depressive symptoms, neuroticism plays a mediating role, and exercise frequency could moderate negative life events and neuroticism.
